The k-esc B in Kermit requests that the serial port transmit a 233ms "break" (pulse) signal regardless of whether emulation is active or not. That's the same RS-232 break you'd get from any "real" terminal be it 33-KSR (a teletype machine) or a VT102 (or any other model). >I tried B with Kermit 3.82 and was immediately disconnected from my >mainframe. Not what I expected. Perhaps the break is too long? Has anyone >else been disconnected with B? Hard to diagnose. Since you indicate that you're current host software doesn't expect a true break signal, it's hard to predict how it deals with one. BREAK is an RS232 function (Kermit envokes it, but your serial port is what sends it). Unless you've a hardware malfunction, 233ms is what you should be getting. Our system uses a true break from hardwired micros as a lead-in to auto baud detection. Since a break is the same at any baud rate, the break causes causes the auto baud detect mechanism to take the next character and match it agains bit patterns for a carriage return at different baud rates (the match sets the rate -- anything from 110 to 9600). Once connected, all sending a break to our system does is generate a parity error requiring a "parity" reset (keyboard unlock). --------------------- Disclaimer: The "look and feel" of this message is exclusively MINE!
